## AI overview

A tutorial explains how to uninstall a Codename One cn1lib extension by removing its library and version files, deleting related build hints, and refreshing the project's client libraries in NetBeans.

## Source excerpt

A while back a question was asked on stack overflow How do you uninstall an extension using the CodenameOne Settings tool in NetBeans? Unfortunately this isn't automatic due to the way cn1libs are implemented. In some cases you need to uninstall a cn1lib if you no longer need its functionality and this is far from seamless. These are the steps you need to take: Remove the files with the name of the extension (the .cn1lib and the .ver file) from the lib directory - you can see them in the files tab in NetBeans or in the file explorer of your OS.
